Talvez deva tentar algumas variações de ortografia:
defense processes » defense process (Expandir a busca), decrease processes (Expandir a busca), disease processes (Expandir a busca)
decrease defense » defense defense (Expandir a busca), decrease release (Expandir a busca), decreases disease (Expandir a busca)
methods sampling » methods comparing (Expandir a busca), methods applied (Expandir a busca), method sample (Expandir a busca)
decrease faster » decrease after (Expandir a busca), decrease further (Expandir a busca), decreased after (Expandir a busca)
faster decrease » rate decrease (Expandir a busca)
python methods » action methods (Expandir a busca), cation methods (Expandir a busca)
sampling error » sampling effort (Expandir a busca)
error program » sector program (Expandir a busca), senior program (Expandir a busca), parfor program (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease faster decrease defense processes ) OR ( python methods sampling error program ))~.
